•
Two split-core current transformers (CTs) for production and
consumption metering
•
Length of DIN rail for mounting
•
Ferrite bead to attach to your Ethernet Cable, if used
• Quick Install Guide (this document)
C ) Check that there is enough space in the switchboard to install CTs.
Do not install the CTs in a panel where they exceed 75% of the wiring
space of any cross-sectional area within the panel.
D ) Install the Envoy-S Metered in an IP54-rated, or better enclosure with
conduit attachment when installing outdoors. Do not drill holes on
the top of the enclosure or anywhere that allows moisture ingress.
Metallic enclosures may impair Wi-Fi signal strength. Use an appropriately rated enclosure if installing the Envoy-S indoors.
E ) If you are installing the Envoy-S in a multi-phase application, make
sure you have the following items:
•
Additional CTs (CT-100-SPLIT) for multi-phase installations. Make
sure you have one CT for each phase monitored, for both production and consumption.
•
A phase coupler. Install a phase coupler on the load side of the
over-current protection device. See the Technical Brief on Phase
Coupling for your region at enphase.com/support. Consult Enphase support for compatible devices.
F ) Decide how to connect the Envoy-S to the Internet: choose to use
Wi-Fi, an Enphase Mobile Connect modem, or Ethernet.
G ) Make sure you have the following optional items, if needed:
•
Enphase Mobile Connect™ modem (order CELLMODEM-02)
•
Ethernet over power line communication (PLC) bridge with Ethernet cables [order EPLC-02 (EU), EPLC-03 (UK) or EPLC-04 (AU/NZ)]
•
Ethernet cable [802.3, Cat5E or Cat6, unshielded twisted pair
(UTP)]. Do not use shielded twisted pair (STP) cable.
H ) Install the PV system as directed by the installation manuals.
I ) If an Enphase PV system is or will be installed at the site, create a
paper installation map to record device serial numbers and positions
in the array. You will scan this map later using Installer Toolkit and
your mobile device.
•
As you did with the microinverters (and Enphase AC Batteries, if
installed), peel the removable label from the bottom of the Envoy-S
and afx it to the paper installation map.
•
Always keep a copy of the installation map for your records.
NOTE: If needed, you can nd an installation map with any Enphase

Clamp the CT on the main supply Line 3 (active). When the
consumption CT is on Line 3 (active) conductor, the arrow must
point towards the load (away from the grid).
•
Tighten all connections to 0.56 Nm.
NOTE: Because of variance in switchboard design and main power
feed, there may not always be enough space to install CTs.
NOTE: It is important to match CT and voltage sense phases. Be
sure to consistently identify all the AC lines at three points: the main
switchboard feed, the Envoy, and the solar production circuit breaker.
Wire colours may not always consistently identify Lines 1, 2 and 3. If in
doubt, use a multimeter to check.
DANGER! Risk of electric shock. Always de-energise circuits
before wiring for power and CTs.
DANGER! Risk of electrocution! Do not install CTs when current
is owing in the sensed circuit. Always install CT wires in the
terminal blocks before energising the sensed circuit.

Device detection issues
If the Device Communications LED lights solid amber, it may be a result of low
light levels. If there isn’t enough sunlight to power up the microinverters, they can’t
communicate with the Envoy.
If there is sufcient daylight for the microinverters to power up, the issue may be that
the Envoy-S is having difculty communicating over the power lines. To troubleshoot
this issue:
•
Check the Installer Toolkit mobile app to see which devices are not
communicating.
•
Check that the circuit breaker(s) for the PV array are in the “ON” position.
•
Verify that the PV modules are connected to the microinverters.
•
Verify the PV module DC voltage is within the allowable range for the microinverter.
c
Power production issues
If the Power Production LED lights solid amber, check the Installer Toolkit mobile
app to see which microinverters are not producing:
•
If none of the microinverters are producing power, there may be a grid or wiring
issue. First, verify that there is proper input voltage and frequency from the grid.
Next, check the breaker and wiring, starting at the switchboard.
•
If all of the non-productive microinverters are on the same branch, check the
breaker and wiring starting at the junction box for the affected branch.
•
If only one or scattered microinverters are not producing power, rst check to see
that the AC connectors are fully seated in the Engage Cable connectors. Next,
check that each module is providing the required startup voltage for the microinverter (22V). A PV module that is failing or that is undersized may not generate
enough power for AC conversion.
d
Internet connection issues
If you are using Wi-Fi and the Network Communications LED remains off:
•
The WPS connection window may have timed out. Retry the connection steps.
•
Make sure that the broadband router is operational by checking that other devices at the site can access the network.
•
Be aware that metal enclosures or obstructions impede wireless communication.
•
If you cannot see your router or access point in the list on the Envoy, or cannot
maintain a connection, it may be necessary to add a wireless repeater to extend
the network range.
If you are using Wi-Fi and the Network Communications LED lights solid amber, make
sure that the broadband router is connected to the Internet by checking that other
devices at the site can access the Internet.
If you are using the Enphase Mobile Connect modem and the Network Communications LED remains off or lights solid amber, see Troubleshooting in the Enphase Mobile
Connect Installation Guide.
For any connection method, you can troubleshoot network issues with the Installer
Toolkit mobile app by tapping the Network button, then Diagnostic Tools.
If you replace the broadband router, congure the Envoy-S Wi-Fi settings for the new
Wireless Network Name (SSID) and password.
